Electric customer choice switch rates and aggregation activity

Ohio Administrative Code 4901:1-25-02 requires electric utilities, competitive retail electric service (CRES) providers, electric cooperatives and governmental aggregators to report monthly market monitoring information to the PUCO on a quarterly basis. Specifically:

  • 4901:1-25-02(A)(2) for electric utilities (known as 1.2 data)
  • 4901:1-25-02(A)(3) for certified retail electric services companies (1.3 data)
  • 4901:1-25-02(A)(4) for certified aggregators and governmental aggregators (1.4 data)

Additionally, Ohio’s electric distribution utilities (EDUs) submit similar data pursuant to Ohio Revised Code 4935 and Ohio Administrative Code 4901:5 (known as SE-1 or forecasting data).

The PUCO may use any of these data sources in assessing whether effective competition exists for retail electric service in Ohio. 

Ohio retail electric service market definition and measurements

Effective competition includes the existence of the following characteristics: (1) participation in the market by multiple sellers so that an individual seller is not able to influence significantly the market price of the commodity; (2) participation in the market by informed buyers; (3) lack of substantial barriers to supplier entry into and exit from the market; (4) lack of substantial barriers that may discourage customer participation in the market; and (5) sellers offering buyers a variety of CRES products.

Measurements of the health of Ohio’s CRES market include: (1) number of Commission-certified CRES providers in Ohio; (2) number of Commission-certified CRES providers by EDU service territory; (3) number of active CRES providers by EDU service territory; (4) number of customers shopping by class, by EDU service territory; and (5) percentage of load shopping by class, by EDU service territory; (6) all EDUs have at least structural separation; (7) 100 percent of the SSO load is procured via a competitive process for all EDUs; and (8) customers are engaged and informed about the products and services that they receive.

Interactive switch rate dashboards

Below are new switch rate dashboards which have replaced the PDF switch rate reports. The dashboards show the number of customers and sales that have shifted from the EDU’s Standard Service Offer (SSO) to a competitive (CRES) product. The SSO represents the default electric generation service a customer will receive from their local electric utility if they do not choose a CRES product. The percentage of customers that have chosen a CRES product is known as the “switch rate.” (Dashboards link to an external site)

No individual metric is determinative of the lack of effective competition or implies that action needs to be taken. Rather, the collective results of the metrics can be used for monitoring purposes to evaluate the effectiveness of competition at a particular time.
